Monitor Series
Compact Two-Way Speaker
MR4/4T
SPEAKER
Careful acoustic design and the use of advanced
materials contribute to the exceptional music fidelity
and speech intelligibility exhibited by the Mackie
Industrial MR4/4T (black) and MR4W/4WT (white)
two-way speaker systems.
The low-frequency driver's carbon fiber diaphragm
remains extremely rigid at high power levels, produc-
ing a more linear response and lower distortion. The
cone is fitted with a durable foam surround and treated
to resist moisture. The high-frequency section features
a constant directivity horn with a built-in mechanical
phase equalizer. The horn is driven by a Ferrofluid
®
cooled, 0.5" Mylar
®
dome tweeter.
The system is nominally crossed over at 4kHz by
a 12 dB/octave network, which uses markedly lower
(than conventional) inductance values in series with
the woofer. This design reduces sound delays associ-
ated with high inductance values and provides excel-
lent low frequency transient response. The high-pass
section is corrected for optimum performance of the
CD horn and is protected with a circuit based on a low-
value/low-mass filament resistor that smoothly limits
the power sent to the tweeter driver.
All components are housed in a vented enclosure
formed from semi-expanded polystyrene foam that is
extremely strong, lightweight and weather resistant.
Threaded metal sockets are molded into the cabinet to
facilitate quick, safe deployment of the MR4/4T, as a
single unit or in arrays, using specially designed acces-
sory mounting hardware.
The MR4/4T is a part of Mackie Industrial’s Monitor
Series, which includes two-way constant directivity,
compact speakers in easily installed enclosures.
